Each channel supports data rates of up to 56 Gbps, satisfying 100G-level high-speed data transmission requirements. With built-in EEPROM functionality for storing and retrieving device information, it operates within a temperature range of 0°C to 70°C, making it suitable for most indoor network environments. Its maximum connection length reaches 3 meters, providing a reliable solution for short-distance, high-speed data transmission.

Analysis of Core Technical Standards

This 100G SFP-DD DAC first and foremost adheres strictly to the SFP-DD MSA protocol. SFP-DD stands for Small Form-factor Pluggable Double Density, a next-generation optical module and cable protocol designed to enhance port density and transmission rates. It achieves double the transmission bandwidth compared to conventional SFP ports while maintaining the same physical footprint, meeting data center demands for high-density, high-bandwidth deployments. Additionally, the product complies with IEE802.3bj (50GBASE-CR2) and IEE802.3cd standards—high-speed Ethernet transmission specifications developed by IEEE—targeting 50G and 100G copper-cable transmission scenarios respectively. This ensures compatibility and stability during high-speed transmission, enabling seamless integration with network devices that meet the same standards and guaranteeing accurate, consistent data transfer.
